Laundry & Cleaning Industry Textile Printing & Dyeing Environmental Protection & Water Treatment
Sodium percarbonate, commonly known as solid hydrogen peroxide, is an addition compound of sodium carbonate and hydrogen peroxide with the chemical formula 2Na₂CO₃·3H₂O₂.
Presenting as white crystalline granules or powder, it is readily soluble in water, releasing oxygen and active oxygen. It acts as a highly efficient and eco-friendly oxidant, bleaching agent, and disinfectant.
Compared with traditional chlorine-containing bleaching agents, it features mild action and zero pollution, serving as a key material for modern green cleaning and industrial oxidation applications.
Core Advantages
High-Efficiency Active Oxygen Source:
It rapidly releases active oxygen upon dissolving in water, featuring strong oxidizing power and remarkable bleaching, stain-removing, and sterilizing effects.
Safety & Eco-Friendliness:
Its decomposition products are oxygen, water, and sodium carbonate—non-toxic, harmless, and free of pungent odors. It will not damage fabric fibers or surfaces and complies with environmental protection standards.
Convenient & Stable for Use:
In solid form, it is safe and easy to transport and store; it also maintains excellent stability under dry conditions.
Multi-Functional All-in-One Solution:
It integrates multiple functions including bleaching, disinfection, decontamination, and odor elimination.

Key Application Fields
FAQ ：Sodium Percarbonate
Q: What is sodium percarbonate, and what are its core characteristics?
A: Sodium percarbonate (CAS No. 15630-89-4), commonly called solid hydrogen peroxide, is an addition compound of sodium carbonate and hydrogen peroxide with the formula 2Na₂CO₃·3H₂O₂. It appears as white crystalline granules or powder, dissolves easily in water to release active oxygen, and acts as a highly efficient, eco-friendly oxidant, bleaching agent, and disinfectant with mild, non-polluting effects.
Q: What industries is sodium percarbonate suitable for?
A: It is widely used in three major fields:
Laundry & cleaning industry: Core ingredient for color-safe bleaching powders, automatic dishwasher detergents, and multi-purpose household cleaners.
Textile printing & dyeing industry: Low-temperature bleaching agent for natural fibers like cotton and linen, and deoxidizer for pre-dyeing processes.
Environmental protection & water treatment: Oxidant for refractory wastewater (cyanide-containing, dye wastewater) and oxygenation agent for pond aquaculture.
Q: Is sodium percarbonate compatible with other detergent ingredients?
A: Yes. It has excellent compatibility with anionic, non-ionic surfactants, builders, and enzymes commonly used in detergents. It does not react with most formulation components and can enhance the overall decontamination and bleaching efficiency of products.
Q: How do you ensure the stability of sodium percarbonate during storage and transportation?
A: Our product maintains good stability under dry conditions. We use sealed, moisture-proof packaging to avoid contact with water and high humidity. The bulk density is adjustable (0.90–1.20 g/cm³) to suit different transportation and mixing requirements. It is safe for transportation as a non-hazardous chemical.
Q: Is sodium percarbonate safe for fabric and surface cleaning?
A: Yes. Compared with traditional chlorine-containing bleaches, it does not damage fabric fibers or fade colored garments. It is also gentle on hard surfaces like kitchen counters and dishware, leaving no corrosive residues and complying with international environmental protection standards.
Q: What are the key quality control indicators besides active oxygen content?
A: Key indicators include moisture content (≤2.0%, tested by loss on drying), iron content (≤20 ppm, tested by atomic absorption spectrometry—low iron content helps maintain product stability), and pH value (10–11 for 30g/L solution, tested by potentiometry).
Q: Do you provide samples for testing?
A: Yes. We offer free or low-cost trial samples with the same specifications as bulk orders. We can also customize sample packaging to support your formulation testing and quality verification.
Q: Can you provide technical support for product formulation?
A: Yes. Our professional technical team can provide guidance on the dosage of sodium percarbonate in different products (e.g., laundry powder, dishwasher detergent) and solve formulation problems such as stability optimization and efficacy enhancement.
